Yes, Troopers made until 1969 had an exposed ejector rod. When I was younger, I thought S&W had the better idea, now I like them.
You don't say what you want them for, but if it's for shooting, go with the S&W for half the money. If it's for collecting, they would need to have their boxes and stuff. As for as future value, that's not why I buy guns, because I'm not smart enough. If the money doesn't matter and you like the Colt better, that's reason enough.
Is the Colt twice the gun, or even a better gun for general shooting? No.
